The typing table is a sleeper piece of mid-century industrial furniture. It's simple, minimal, and versatile. It has sidewings that fold down and wheels which lock in place. But what I like most about it is that it's all metal.

Used in offices during the 40's and '50s for secretaries to wheel their typewriters around on, the typing table can be repurposed as as a stand/table/cart/tray in the living room/bedroom/bathroom/kitchen/garage. These seem to be going from anywhere between $70 and $90 on eBay, but if you put in your due diligence on Craigslist, you can probably find one for $30 or $40, maybe cheaper. (I actually found one for $15 once) [Etsy]
